Key Features and Benefits

• Multi-equipment capabilities support general HVAC applications including complex central plants.
• 10/100Base-T Fast Ethernet provides high speed communications to controller; ideal for critical control applications.
• 10/100Base-T Fast Ethernet allows modules to serve as a BACnet router between BACnet/IP system backbone and field devices subnetwork.
• Native BACnet communications to field devices over a high-speed ARCNET 156 Kbps or BACnet MS/TP network.
• Protocol translator package allows the ME controllers to serve as a gateway between BACnet and a wide range of open and proprietary networks.
• Controller units include an expansion port for MEx I/O expanders or previous generation MX expanders. Up to six MEx expanders can be mounted in a stack or remotely mounted for scalable control solutions.
• Designed with a high-speed true 32-bit microprocessor with cache memory, Fast Ethernet controller, high performance 32-bit serial communications co-processor, ARCNET communications co-processor and CAN (Control Area Network) co-processor, ME-LGR controllers have the horsepower to serve the most demanding control applications.
• 16 MByte battery-backed SDRAM (32 bit wide), with 12 MBytes available for use, stores application programs, trends and other data when power is lost.
• 8 MByte Flash memory (32 bit wide) for easy field upgrades over the network.
• Battery backed real-time clock provides true standalone capabilities. Control modules recover from power failures providing full continuity of operations, even when communications are disrupted.
• Rnet port supports Automated Logic’s line of RS room sensors and BACview6 local operator interface, and provides local access to the system. Enhanced local access is also available on EIA-232 port.
• ME line controllers are fully graphically programmable and offer full peer-to-peer communications with other ME line, SE line or ZN line controllers. Graphical programs are universally understood and provide self-documenting control sequences.
• Tough construction delivers superior performance and reliability. Modules are constructed with a rugged aluminum cover which provides optimum electrical protection and noise immunity.

Combining the features of our powerful multi-equipment controller with a high-speed BACnet router, the ME-LGR can do it all. Need 100 Mbps communications to a critical control site? Need to control multiple pieces of equipment at that site? Need to integrate third-party equipment on a proprietary network with your BACnet system? No problem. The ME-LGR can do it all, and it can also serve as a router to controllers on an ARCNET 156 Kbps or MS/TP network.
